Preamp topology

How did they model a few of these preamps from something real ? As in preamp #5 .
Entire 1974 amp with no feedback into a dummy load with the 1959’s tonestack

From Surfs link - The core of the technology captures the exact harmonics of each amplifier .

Is there a way to run a 1974 into a dummy load and then into a 1959 tonestack ?

I am sure they have some propriety software and procedure they use when capturing the amps voice.

There are probably a lot of ways to create a preamp/amp model. One current product, the Kemper, has a function where you can record an amp's tone (even something off a record), and it can create an algorithm to recreate that amp's tone. Or you can use it to model a live amp in order to clone its tones. Many players swear by the Kemper.

Another process would be to recreate components and their sonic characteristics in software. You could then assemble a virtual amp in software, and model how those components would interact in a real amp.

Of course the various modeler developers will not give out hard information on how they do what they do. The Softube description, while interesting, reads to me as sales/marketing fluff and does not at all give real hints of what they do. That is normal for most high tech manufacturers.

I am curious as to why the folks at Marshall picked nonexistent amps to model (like in the OP), as well as standard amps with pedals in front. I really wish they would have included models of obvious EL34 based vintage amps like the 50W and 100W Super Leads.

Wouldn't it be cool if in future Marshall modeling amps, if they made presets to correspond with famous player's amp tones? Have a preset for the Hendrix Super Lead tone, another for Angus Young, yet another for Garry Moore, and throw in Page's SRTS tone. The mind boggles at the possibilities.

The Kemper is really good. When I push it into my slave amp its about as good as it gets for any tone.

Demos of the Kemper....seemed pretty sterile, lifeless and little mojo.
